Basic Concepts
• The communications power supply must be 24 V DC.
• Always supply the power from the trunk line.
• When providing power to several nodes from one power supply, try to

• The power supply capacity for cables is restricted to 8 A for Thick Cables,
• Environment-resistive Slaves are wired with Thin Cable, so the current
• A single network is usually supplied by one power supply, however, it is

there is one communications power supply in the system and the current
consumption is within the specifications of the T-branch Tap or T-branch
Connector. Refer to 2-3-4 T-branch Taps or 2-3-5 Shielded T-branch Con-
nectors for details on the current limitations of these components.

on its length. Use the following equation to calculate the current capacity.
(The maximum current capacity of a branch line is 3 A, even if the branch
line is shorter than 1.53 m.)
I = 4.57/L
I: Permissible current (A)
L: Length of the branch line (m)
